Abstract
A method for manufacturing liquid discharge heads having a substrate where energy generation elements that generate energy used for discharging liquid are formed, a wiring electrically connected to the energy generation elements, and a flow path communicating with discharge ports for discharging liquid and corresponding to the energy generation elements. The method includes forming a resin layer on the substrate, a first pattern for forming the wiring on the resin layer, the wiring on the substrate using the first pattern, a second pattern for forming the flow path on the resin layer, a coating layer for coating the second pattern, and the flow path by removing the second pattern.
